Some companies may have more specific requirements for some other trace elements, which can be coordinated with customers and electroplating plants during actual production. In general, blue plating will be easier than white zinc testing requirements. In addition, the environmental protection requirements of plastic raw materials, standard requirements of conventional element content: Cl content is less than 900, S content is less than 10000, Cr content is less than 700, As content is less than 1000, Br content is less than 900, Cd content is less than 50, Hg content is less than 700, Pb content is less than 200, Sn content is less than 900, Sb content is less than 700, because in the production process, color matching is also needed.
